Stability and Mobility of Mutagenic Activity from Wastewater and Sludge in Agricultural Soils

摘要

The objective of the research was to measure the fate and mobility of organic mutagens in municipal sludge amended soil. The results indicate that municipal sludges may contain a persistent mutagenic residue. In addition, leaching of mutagens may be a serious problem in coarse textured soils, or in areas which receive high amounts of rainfall. Uptake of mutagens into plants does not appear to be a significant problem for the sludges, soils, plants, and application rates employed, as none of the extracts of plants grown on sludge amended soil induced a positive response.
